Abstract
Image acquisition system (202) captures target image (402) and generates (206) best-fitting avatar (404) using the methods described above. Best-fitting avatar is geometrically normalized by backing out deformations corresponding to non-intrinsic and non-permanent features of the target head (406). The geometrically normalized avatar is lit with normal lighting (406), and projected into an image plane corresponding to a normal pose, such as a face-on view. The resulting image (408) is geometrically normalized with respect to shape (expressions and temporary surface alterations) and pose, as well as photometrically normalized with respect to lighting.
